In the standard setting (P428 =
0
Off
) the inverter requires a flank to enable (signal change
from "low
high") at the relevant digital input.
In the setting
On
1
the FI reacts to a High level. This function is only possible if the FI is
controlled using the digital inputs. (see P509=0/1)
In certain cases, the FI must start up directly when the mains are switched on. For this P428 =
1
On
can be set. If the enable signal is permanently switched on, or equipped with a cable
jumper, the FI starts up immediately.
NOTE:
(P428) not "ON" if (P506) = 6,
Danger!
(See note on (P506))
NOTE:
The "Automatic Start" function can only be used if a digital input of the frequency
inverter (DIN 1 …) is parameterised to the function "Enable Right" or "Enable Left"
and this input is permanently set to "High". The digital inputs of the technology
modules (e.g.: SK CU4 - IOE) do not support this "Automatic Start" function!
NOTE:
The "Automatic Start" function can only be activated if the frequency inverter has
been parameterised to local control ((P509) setting { 0 } or { 1} ).

Settings 3 to 5 and 11 work with a 10% hysteresis, i.e. the output delivers (function 11 does not deliver)
when the 24V limit value is reached and switches off again when the value drops to a value that is 10
% less again (function 11 on again).
This behaviour can be inverted with a negative value in P435.

1 = External brake
, to control an external 24V brake relay (max. 20 mA). The
output switches at a programmed absolute minimum frequency (P505).
For typical brakes a setpoint delay of 0.2-0.3s should be programmed (see
also P107/P114).
Low
2 = Inverter operating
, the output indicates voltage at the FI output (U - V - W).
High
3 = Current limit
, based on the setting of the motor rated current (P203). This
value can be adjusted via the standardisation (P435).
High
4 = Torque current limit
, based on motor data settings in P203 and P206.
Signals a corresponding torque load on the motor. This value can be adjusted
with the standardisation (P435).
High
5 = Frequency limit
, based on motor nominal frequency setting in P201. This
value can be adjusted via the standardisation (P435).
High
6 = Setpoint reached
, indicates that the FI has completed the frequency increase
or decrease. Setpoint frequency = actual frequency! From a difference of 1 Hz
Setpoint value not achieved

7 = Error,
general error message, error is active or not yet acknowledged.

8 = Warning:
general warning, a limit value was reached that could lead to a later
shutdown of the FI.

9 = Overcurrent warning
: At least 130 % of the nominal FI current was supplied
for 30 s.
